	  CPU reset exception vector (e.g. U-Boot as ROM loader in Qemu,

	  This is the base address for a memory block, which is used for

	  block which is used for loading and filling cache lines when
	  SYS_MIPS_CACHE_INIT_RAM_LOAD is selected.

	---help---
	  A table of relocation data will be appended to the U-Boot binary
	  and parsed in relocate_code() to fix up all offsets in the relocated
	  U-Boot.

	  This option allows the amount of space reserved for the table to be
	  adjusted in a range from 256 up to 64k. The default is 32k and should
	  be ok in most cases. Reduce this value to shrink the size of U-Boot
	  binary.

	  The build will fail and a valid size suggested if this is too small.

	  If unsure, leave at the default value.
